6 Safety Precautions and Instructions TP-6843 1/13
Battery gases. Explosion can
cause severe injury or death.
Battery gases can cause an explosion.
Do not smoke or permit flames or
sparks to occur near a battery at any
time, particularly when it is charging.
Do not dispose of a battery in a fire.
To prevent burns and sparks that
could cause an explosion, avoid
touching the battery terminals with
tools or other metal objects. Remove
all jewelry before servicing the
equipment. Discharge static electricity
from your body before touching
batteries by first touching a grounded
metal surface away from the battery.
To avoid sparks, do not disturb the
battery charger connections while the
battery is charging. Always turn the
battery charger off before
disconnecting the battery connections.
Ventilate the compartments containing
batteries to prevent accumulation of
explosive gases.
Battery short circuits. Explosion
can cause severe injury or death.
Short circuits can cause bodily injury
and/or equipment damage.
Disconnect the battery before
generator set installation or
maintenance. Remove all jewelry
before servicing the equipment. Use
tools with insulated handles. Remove
the negative (–) lead first when
disconnecting the battery. Reconnect
the negative (–) lead last when
reconnecting the battery. Never
connect the negative (–) battery cable
to the positive (+) connection terminal
of the starter solenoid. Do not test the
battery condition by shorting the
terminals together.
Engine Backfire/Flash
Fire
Servicing the air cleaner. A sudden
backfire can cause severe injury or
death. Do not operate the generator
set with the air cleaner removed.
Servicing the fuel system. A flash
fire can cause severe injury or
death. Do not smoke or permit flames
or sparks near the carburetor, fuel line,
fuel filter, fuel pump, or other potential
sources of spilled fuels or fuel vapors.
Catch fuels in an approved container
when removing the fuel line or
carburetor.
Combustible materials. A fire can
cause severe injury or death.
Generator set engine fuels and fuel
vapors are flammable and explosive.
Handle these materials carefully to
minimize the risk of fire or explosion.
Equip the compartment or nearby area
with a fully charged fire extinguisher.
Select a fire extinguisher rated ABC or
BC for electrical fires or as
recommended by the local fire code or
an authorized agency. Train all
personnel on fire extinguisher
operation and fire prevention
procedures.
Exhaust System
Generator set operation. Carbon
monoxide can cause severe
nausea, fainting, or death. Carbon
monoxide is an odorless, colorless,
tasteless, nonirritating gas that can
cause death if inhaled for even a short
time. Avoid breathing exhaust fumes
when working on or near the generator
set. Never operate the generator set
inside a building. Never operate the
generator set where exhaust gas
could seep inside or be drawn into a
potentially occupied building through
windows, air intake vents, or other
openings.
Carbon monoxide detectors.
Carbon monoxide can cause severe
nausea, fainting, or death. Install
carbon monoxide detectors on each
level of any building adjacent to the
generator set. Locate the detectors to
adequately warn the building’s
occupants of the presence of carbon
monoxide. Keep the detectors
operational at all times. Periodically
test and replace the carbon monoxide
detectors according to the
manufacturer’s instructions.
Carbon monoxide symptoms.
Carbon monoxide can cause severe
nausea, fainting, or death. Carbon
monoxide is a poisonous gas present
in exhaust gases. Carbon monoxide
is an odorless, colorless, tasteless,
nonirritating gas that can cause death
if inhaled for even a short time.
Carbon monoxide poisoning
symptoms include but are not limited
to the following:
• Light-headedness, dizziness
• Physical fatigue, weakness in
joints and muscles
• Sleepiness, mental fatigue,
inability to concentrate or speak
clearly, blurred vision
• Stomachache, vomiting, nausea
If experiencing any of these symptoms
and carbon monoxide poisoning is
possible, seek fresh air immediately
and remain active. Do not sit, lie
down, or fall asleep. Alert others to
the possibility of carbon monoxide
poisoning. Seek medical attention if
the condition of affected persons does
not improve within minutes of
breathing fresh air.
Fire.
Can cause severe injury or death.
Do not smoke or permit flames or
sparks near fuels or the fuel system.
Carbon monoxide.
Can cause severe nausea,
fainting, or death.
The exhaust system must be
leakproof and routinely inspected.
